Sub-partitioning of wireless wideband channel and usage

ABSTRACT

A communication management resource associated with a wireless access point in a network environment allocates use of a wireless channel and sub-channels over time to multiple communication devices in communication with the wireless access point. For example, during use, from a first communication device of the multiple communication devices competing for wireless bandwidth, the communication management resource receives a request for allocation of wireless bandwidth to communicate over a wireless communication link with the wireless access point. Subsequent to receiving the request, the communication management resource identifies an appropriate amount of wireless bandwidth suitable to satisfy the request for bandwidth from the first communication device. In accordance with the identified amount of wireless bandwidth needed to satisfy the request, the communication management resource subdivides the wireless channel for use by the first communication device and potentially other communication devices that request use of the available wireless bandwidth.

BACKGROUND

Conventional wireless networks typically include multiple communication resources (such as one or more WiFi™ access points) facilitating wireless communications with one or more mobile communication devices in a respective wireless region. For example, a conventional wireless network may include: a first wireless access point providing wireless coverage to a first region in a network environment; a second wireless access point providing wireless coverage to a second region in the network environment; etc.

Via communications through a selected one of the multiple base stations, a respective user of the mobile communication device in the home environment is able to wirelessly communicate through a wireless access point over the Internet.

In certain instances, multiple communications devices reside within the same region of wireless coverage of a respective wireless access point. In such an instance, according to conventional techniques, the multiple communication devices compete amongst each other for use of a single available wireless channel to convey communications to the respective wireless access point. The bandwidth of the single available wireless channel may vary depending upon how much of the available bandwidth is required by a respective client device requesting use of the wireless channel.

Additionally, the bandwidth of the single available channel may vary depending upon the degree of interference with other wireless devices using the available wireless bandwidth.

BRIEF DESCRIPTION OF EMBODIMENTS

Conventional techniques of allocating bandwidth in a wireless network environment suffer from deficiencies. For example, according to conventional techniques as previously discussed, each of multiple communication devices must use the same WiFi™ channel at different times in order to communicate with a respective wireless access point allocating use of the channel. Further, according to conventional WiFi™ standards, the minimum amount of bandwidth that can be allocated for use by the multiple communication devices is 20 MHz. These two attributes (i.e., shared use of the same channel and minimum bandwidth of 20 MHz) of a conventional WiFi™ communication system make it very inefficient for low bandwidth, low latency type of wireless applications.

Embodiments herein deviate with respect to conventional techniques to provide a more efficient use of the available wireless spectrum. For example, embodiments herein include enhancing the current WiFi™ specification to allow efficient use of an available wireless spectrum by multiple narrowband/wideband WiFi™ devices competing to communicate with a respective wireless access point.

More specifically, in accordance with one example embodiment, a communication management resource such as associated with a wireless access point in a network environment allocates use of a wireless channel over time to multiple communication devices. The communication management resource receives a request from a first communication device for allocation of wireless bandwidth to communicate over a wireless communication link. In response to receiving the request, the communication management resource then identifies an amount of wireless bandwidth suitable to satisfy the request for bandwidth from the first communication device. In contrast to conventional techniques, and in accordance with the identified amount of wireless bandwidth needed to satisfy the request, the communication management resource subdivides the wireless channel for use by the first communication device and potentially other devices as well.

In one embodiment, the wireless channel is a channel of predetermined bandwidth (such as a minimum bandwidth 20 MHz channel) available for use by multiple communication devices in the network environment. In these circumstances in which the identified amount of wireless bandwidth is substantially less than full capacity of the wireless channel, instead of allocating the whole available channel, the wireless access point allocates an appropriate less-than-all portion of the wireless channel to the first communication device. The first communication device then uses the allocated less-than-all portion of the wireless channel (i.e., an allocated sub-channel) to communicate data over the wireless communication link to the wireless access point.

In accordance with further embodiments, the wireless channel is subdivided for simultaneous use by multiple communication devices. For example, in one embodiment, the less-than-all portion of the wireless channel allocated for use by the first communication device is a first portion of the wireless channel. The communication management resource can be configured to allocate a second portion of the wireless channel for simultaneous use by a second communication device of the multiple communication devices. Subsequent to allocation as previously discussed, the first communication device uses the first portion of the wireless channel to communicate data to the respective wireless access point. Additionally, the second communication device uses the second portion of the wireless channel to communicate data to the wireless access point while the first communication device uses the first portion of the wireless channel to communicate with the wireless access point.

Accordingly, in contrast to conventional techniques, instead of sharing a single channel, embodiments herein include subdividing a respective available channel (such as a channel of minimal size or other standard channel) into multiple portions (sub-channels) and allocating such portions for use by multiple communication devices to simultaneously communicate with the wireless access point.

In yet further embodiments, in response to detecting completion of the first communication device using the less-than-all portion of the channel to transmit a data payload, the communication management resource relocates the less-than-all portion of the channel or possibly combines the less-than-all portion with other available bandwidth to produce a new sub-channel of yet different bandwidth capacity for a same or different communication device.

As further discussed herein, a size of the sub-channels assigned for simultaneous use by each of the multiple communication devices can vary depending upon attributes of the communication device and/or a corresponding application requesting use of wireless bandwidth. For example, in one embodiment, the communication management resource identifies a classification type of an application on a respective communication device generating the request for allocation of the wireless bandwidth. The communication management resource then maps the identified classification type to corresponding flow service settings associated with the application and/or identified device type. As specified by the flow service settings, the communication management resource allows conveyance of communications over one or more subdivided portions of the wireless channel allocated for use by the first communication device.

As further discussed herein, the communication management resource can receive notification that the first communication device is in wireless communication with a second communication device. In such an instance, the first communication device resides in a communication path between the wireless access point and the second communication device. In a downstream direction, the first communication device relays messages from the wireless access point to the second communication device. In an upstream direction, the first communication device relays messages from the second communication device to the wireless access point. Thus, embodiments herein can include serial wireless connectivity and shared use of available bandwidth amongst multiple communication devices.

As further discussed below, embodiments herein provide more flexibility of using an available wireless bandwidth (such as a wireless channel) amongst multiple users competing to communicate with a respective wireless access point.

DETAILED DESCRIPTION AND FURTHER SUMMARY OF EMBODIMENTS

Embodiments herein provide a more efficient use of available wireless spectrum in a wireless communication system, including those that support WiFi-like communications. For example, in accordance with one embodiment, a communication management resource managing communications associated with a wireless access point (such as a modified WiFi™ access point) in a network environment allocates use of a wireless channel over time to multiple communication devices. Assume that the communication management resource receives a request originating from a first communication device of multiple communication devices competing for use of available bandwidth associated with the wireless access point. To fulfill the request of the first communication device, the communication management resource identifies an amount of wireless bandwidth to satisfy the request for bandwidth from the first communication device.

In one embodiment, the amount of allocated bandwidth depends upon one or more factors such as the type of the communication device, type of data being transmitted, type of application testing to transmit the data, a type of subscription purchased by the owner of the first communication device, etc.

In contrast to conventional techniques, and in accordance with the identified amount of wireless bandwidth needed or appropriate to satisfy the request, the communication management resource subdivides the wireless channel for use. At least a portion of the subdivided wireless channel is allocated for use by the first communication device. Further embodiments herein include subdividing the available channel into multiple sub-channels and providing appropriate notifications indicating that the multiple sub channels are available for use by multiple communication devices to simultaneously communicate with the wireless access point.

Now, more specifically, FIG. 1 is an example diagram illustrating a network environment and simultaneous use of a partitioned wireless channel by multiple communication devices according to embodiments herein.

As shown, network environment 100 includes wireless access point 105-1, which is one of multiple wireless access points in the network environment 100. The wireless access points in the network environment 100 collectively provide communication devices 120 access to network 190 (which may include the Internet as well as any other number of networks).

Further in this example embodiment, assume that each of the communication devices 120 establishes a respective wireless communication link with the wireless access point 105-1.

For example, as shown, the communication device 120-1 establishes a respective wireless communication link 127-1 with wireless access point 105-1; the communication device 120-2 establishes a respective wireless communication link 128 with wireless access point 105-1; the communication device 120-3 establishes a respective wireless communication link 129 with wireless access point 105-1; and so on.

Such communication links can be established in accordance with any suitable wireless protocol.

As shown, network environment 100 further includes gateway resource 150. As its name suggests, gateway resource 150 provides and/or controls access to remote network 190 such as the Internet. For example, in one embodiment, when allocated bandwidth, the mobile communication device 120-1 (i.e., device B such as a refrigerator) transmits communications to the wireless access point 105-1 over respective wireless communication link 127-1. In such an instance, the wireless access point 105-1 forwards the payload data (data packets, blocks of data, etc.) in wireless communications from the mobile communication device 120-1 through gateway resource 150 to network 190, where corresponding data packets are distributed to the appropriate one or more target destinations.

In a reverse direction, the wireless access point 105-1 receives communications directed to the mobile communication device 120-1 from network 190. The wireless access point 105-1 conveys the communications over the respective wireless communication link 127-1 to mobile communication device 120-1.

Note that the network environment 100 and corresponding wireless access points including wireless access point 105-1 can be configured to support short-range or a long-range communications in accordance with any suitable wireless protocol. In one non-limiting example embodiment, the wireless access point 105-1 can be configured to support wireless communications in accordance with any of one or more (modified or not) WiFi™ protocols. If desired, the antennas associated with the wireless access points 105 can support beamforming or spatial division multiple access techniques such that frequencies can be reused in different directions in the network environment 100.

In one embodiment, to provide spatial isolation amongst multiple mobile communication devices and wireless access points in network environment 100, embodiments herein can include implementing spatial division multiple access (SDMA) techniques (such as those implementing MU-MIMO) when allocating use of subdivided portions of respective wireless channels. The spatial isolation resulting from spatial division multiple access techniques prevents interference amongst wireless interference and supports reuse of the available wireless spectrum. To notify resources (such as mobile communication devices, wireless access points, etc.) of the presence and availability of respective wireless access points 105, each of the wireless access points repeatedly (over time) can be configured to generate and broadcast communications (such as wireless beacons) in network environment 100. In one embodiment, the signals, such as beacons, include an SSID (name or unique identifier value) assigned to the respective wireless access point transmitting the communication. Accordingly, each of the communication devices 120 is aware of the presence of the wireless access point 105-1 in network environment 100.

In certain instances, subsequent to learning of a presence and availability of a particular wireless access point in its vicinity, a corresponding communication device can initiate further communications with the particular wireless access point to retrieve additional information if desired. The additional information can include a BSSID (such as a unique network address) assigned to the respective wireless access point, vendor information indicating a vendor to which the particular wireless access point is assigned, etc.

In accordance with yet further embodiments, the wireless access point 105-1 can be configured to, in any suitable manner, notify the communication devices 105 of channel partitioning capability as further discussed herein. In contrast to conventional WiFi™ communication systems, the channel partitioning capability as described herein enables multiple different types of communication devices to simultaneously communicate over multiple dynamically allocated channels and/or sub-channels with the wireless access point.

More specifically, assume that the communication device 120-1 (device B assigned network address 2225) would like to transmit data in an uplink direction on wireless communication link 127-1 to the wireless access point. In such an instance, the communication management resource 140 receives a first bandwidth request originated by a respective application in communication device 120-1. The communication device transmits the request over the communication link 127-1. Assume further that the communication device 120-2 (device D assigned network address 8446) would like to transmit data in uplink direction on wireless communication link 128 to the wireless access point 105-1. The communication device 120-2 transmits the request over communication link 128 to the wireless access point. The communication management resource 140 receives the second bandwidth request originated by a respective application in communication device 120-2.

In response to receiving the first bandwidth request from the first communication device 120-1 and second bandwidth request from a second communication device 120-2 for use of available wireless bandwidth in network environment 100, the communication management resource 140 subdivides an available wireless spectrum (such as a single variable bandwidth channel) to include at least a first wireless sub-channel and a second wireless sub-channel for simultaneous use by the communication device 120-1 and communication device 120-2.

Subsequent to subdividing the available wireless bandwidth, the communication management resource 140 allocates the first wireless sub-channel for use by the first communication device 120-1. Additionally, the communication management resource 140 allocates the second wireless sub-channel for use by the second communication device.

Subsequent to allocation of the sub-channels, each of the first communication device 120-1 and second communication device 120-2 simultaneously use the first wireless sub-channel and the second wireless sub-channel to communicate data to the wireless access point 105-1. In a manner as previously discussed, in the upstream direction, the wireless access point 105-1 further transmits the received data through gateway resource 150 to network 190.

Note that, although the communication management resource 140 is shown as being located in the wireless access point 105-1, the communication management resource 140 can reside at any suitable location. For example, the communication management resource 140 alternatively can be located in the gateway resource 150, in a respective communication device itself, or in its own separate communication path with respect to any of the resources in network environment 100.

In accordance with further embodiments, allocation of sub-channels can depend upon a number of factors. For example, in one embodiment, the communication management resource 140 controls allocation of the available bandwidth based upon any of one or more parameters such as a type of the corresponding communication device, the type of application transmitting corresponding data, the type of data being transmitted, subscription level of the corresponding owner of the communication device, etc., over a respective wireless link to the wireless access point 105-1.

In one embodiment, each of the communication devices 120 is assigned different network address information. The respective network address information assigned to a communication device can be encoded in such a manner that it is possible to identify a corresponding device type of the communication device requesting bandwidth. As described herein, certain types of communication devices such as communication device 120-1 may require only low bandwidth (such as less than 3 MHz bandwidth) wireless capability. In contrast, communication devices such as communication device 120-2 and communication device 120-3 (such as computer devices operating respective browser applications) require much higher bandwidth (such as greater than 10 MHz bandwidth).

As a more specific example, assume that the communication device 120-1 generates and transmits a request over wireless communication link 127-1 to the wireless access point 105-1 for allocation of first wireless bandwidth. The request can include identifier information (such as part of a network address) indicating the type associated with the communication device. In this example embodiment, the communication device 120-1 transmits the unique identifier value such as network address information 2225 along with the request over wireless communication link 127-1 to the communication management resource 140.

Further in this example embodiment, to determine the type of device transmitting the request for bandwidth, the communication management resource 140 accesses and utilizes the device information 171 stored in repository 180. In general, FIG. 2 is an example diagram illustrating an example of device information 171 according to embodiments herein.

Using the device information 171 and the received network address 2225 or other suitable device type identifier, the communication management resource 140 is able to identify a device classification type assigned to the communication device 120-1. In one embodiment, the first digit “2” indicates in the network address information 2225 indicates that the device type is a refrigerator. Accordingly, embodiments herein can include utilizing network address information received from the first communication device 120-1 (and mask such as 2XXX) to identify a classification type assigned to the first communication device 120-1. As mentioned, the device information 171 in this example indicates that the communication device 120-1 (assigned network address 2225) is a refrigerator known to require only low bandwidth conveyance of data.

Assume further that the communication device 120-2 generates and transmits a request over wireless communication link 128 to the wireless access point 105-1 for allocation of wireless bandwidth. As previously discussed, the request can include identifier information indicating the classification type associated with the communication device 120-2. In this example embodiment, the communication device 120-2 transmits the network address information 8446 along with the bandwidth request over wireless communication link 128 to the communication management resource 140.

To determine the type of device transmitting the request for bandwidth, the communication management resource 140 accesses the device information 171 stored in repository 180. Using the device information 171 (in FIG. 2) and the received network address information 8446 (assigned to device D), the communication management resource 140 is able to identify a device classification type assigned to the communication device 120-2. In one embodiment, the first digit “8” in the network address information 8446 indicates that the device type is a computer device (supporting applications such as browsers that retrieve and playback content on a media player application). Accordingly, embodiments herein include utilizing a network address received from the first communication device 120-2 (and applying mask 8XXX or other suitable processing) to identify a classification type and bandwidth eligibility assigned to the first communication device 120-2. If desired, the device information 171 in this example can further indicate that the communication device 120-2 (assigned network address 8446) is a computer device known to require high bandwidth conveyance of data.

As further discussed herein, the communication management resource 140 can be configured to take into account the classification type of the communication device requesting wireless bandwidth when subdividing available wireless bandwidth for use by each of the different communication devices. For example, as previously discussed, it may be known that the communication device 120-1 (which is a refrigerator) may require use of only low bandwidth (such as less than 5 MHz) to convey data. Conversely, it may be known that the communication device 120-2 (which is a mobile computer) may require high bandwidth (such as greater than 15 MHz) to convey data.

In one embodiment, the communication management resource 140 utilizes the determined device classification type at least in part to determine how to partition a respective channel into multiple sub-channels for use by competing communication devices 120.

As further discussed below, note that the communication management resource 140 can be configured to use further information (such as service-level information 172) to determine how to fairly partition available wireless bandwidth (such as one or more channels) for use by each of the multiple communication devices 120.

For example, FIG. 3 is an example diagram illustrating an example of service level information 172 correlating application/data to service level information according to embodiments herein. In addition to, or as an alternative to using the network address information or corresponding device type information received from the communication device requesting bandwidth, the communication management resource 140 can be configured to process a respective bandwidth request, and potentially identify from the request communication itself, information such as a type of application making the request for bandwidth, a type of data to be transmitted, etc. This further information can be used as a basis to identify how much bandwidth to allocate to a respective requesting communication device.

Using service level information 172 as shown in FIG. 3, in this example embodiment, the communication management resource 140 maps respective information such as application/data/subscriber type (as determined from a received communication from the requesting communication device) to the appropriate service level, security, etc., to be provided to the requesting communication device. The appropriate level of service can indicate a level of quality of transmitting data, latency of transmitting data, security Lowell associated with transmitting data for a particular type of communication device, etc.

Accordingly, the communication management resource 140, when identifying an amount of bandwidth to allocate for use by respective communication devices, can be configured to identify service level settings associated with an application and/or mobile communication device generating the request for the wireless bandwidth. The communication management resource 140 then subdivides the wireless channel in accordance with the service level settings as further discussed below.

In one embodiment, security parameters can be tied to device type in addition to the usual security parameters that apply to service flow. For example, in one embodiment, when allocating use of subdivided portions of one or more wireless channels to the communication devices 120, the communication management resource 140 identifies a classification type associated with the communication device generating the request for allocation of the wireless bandwidth. The communication management resource 140 utilizes the service-level information 172 to identify security setting information assigned to the identified classification type of the requesting communication device. As specified by the identified security setting information assigned to the type associated with communication device, the communication manager resource 140 implements the specified security (as indicated in service-level information 172) when transmitting communications over a subdivided portion of the wireless channel to the requesting communication device. As mentioned above, the security parameters tied to the device type can be in addition to usual security parameters that apply to a respective service flow.

FIG. 4 is an example diagram illustrating allocation of one or more channels/sub-channels over multiple frames to multiple communication devices according to embodiments herein.

As further shown, the communication management resource 140 allocates use of the wireless spectrum (such as a selected channel bandwidth of 20 MHz, minimum sized WiFi™ channel, 40 MHz, 80 MHz, 160 channel, etc.) in different time frames for use by the different communication devices 120.

For example, for frame #1, the communication management resource 140 allocates use of channel A-D (such as a 20 MHz channel to communicate between device D and device A) for use by the communication device 120-2. Prior to allocation and use of bandwidth in frame #1, the communication management resource 140 potentially allocates the wireless channel for use by another communication device such as communication device 120-2 in frame #0 or prior.

Subsequent to allocation in frame #0, during frame #1, the communication device 120-2 transmits corresponding data over the wireless communication link 128 using allocated channel A-D (such as a full 20 MHz channel). If needed, note that the communication device 120-2 can be allocated use of the 20 MHz channel A-D for multiple back-to-back time frames. That is, during frame #0 and #1, the communication device 120-2 transmits data using a center carrier frequency CF1 (such as in the center of the corresponding allocated 20 MHz band).

Further, in a manner as previously discussed, the communication device 120-1 can be configured to generate and forward a request for bandwidth to the communication management resource 140. In response to receiving the request for bandwidth (such as during frame #1 or prior), and to accommodate the request, for frame #2, the communication management resource 140 subdivides the 20 MHz channel into a first sub-channel A-B (such as a 2 MHz sub-channel) and a second sub-channel of A-D (such as an 18 MHz sub-channel).

In one embodiment, the whole 20 MHz channel may originally be allocated for use by the communication device 120-2. Because the communication device 120-1 is identified as a low latency device or requires high priority data transmissions, as shown between frame #1 and the #2, the communication management resource 140 can be configured to reduce the amount of bandwidth allocated to communication device 120-2 during frame #2 to accommodate the needs of the communication device 120-1.

The communication management resource 140 then notifies communication device 120-1 that it is assigned to communicate in frame #2 using the 2 MHz sub channel A-B; the communication management resource 140 notifies communication device 120-2 has been assigned to communicate in frame #2 using the adjusted 18 MHz sub channel A-D. Note that splitting of the original channel to accommodate the communication device 120-1 in frame #2 requires that the communication device 120-1 use center frequency CF2 instead of center frequency CF1. The communication management resource 140 notifies the communication device 120-1 to communicate using center frequency CF3 in frame #2.

Accordingly, as shown in frame #2, the communication management resource 140 allocates the first wireless sub-channel A-B to the first communication device 120-1 and the second wireless sub-channel A-D to the second communication device 120-2. In accordance with the allocation of sub-channels in frame #2, the communication device 120-1 and the communication device 120-2 simultaneously communicate data over the available wireless bandwidth to the wireless access point 105-1. The wireless access point 105-1 simultaneously receives first communications over the first sub-channel A-B from the first communication device 120-1 and second communications over the second sub-channel A-D from the second communication device 120-2.

As previously discussed, note again that the communication management resource 140 may initially allocate the whole channel in frame #1 for use by the second communication device 120-2. Thus, the wireless channel A-D can be initially allocated for use by a second communication device to communicate with the wireless access point 105-1 at or around a time of receiving the request for bandwidth from communication device 120-1. In such an instance, to accommodate the request for wireless bandwidth from the first communication device 120-1, the communication management resource 140 allocates a less-than-all portion (2 MHz) of the available 20 MHz wireless channel to the first communication device 120-1 for use in the second frame. Thus, the communication management resource 140 reduces the amount of bandwidth in the wireless channel (original 20 MHz channel assigned in frame #1) to 18 MHz channel in frame #2 such that the remaining 2 MHz of bandwidth (channel A-B) was available for use in frame #2 by the first communication device 120-1. This partitioning of channels into corresponding sub-channels on an as-needed basis accommodates devices that need a relatively small amount of bandwidth, but need it immediately.

As previously discussed, the apportionment of available bandwidth by the communication management resource 140 can depend upon any number of factors such as the network address of the communication device requesting bandwidth, an identified classification type of the communication device requesting bandwidth, the type of data being transmitted, the classification of an application requesting the band with, priority assigned to the subscriber using the corresponding communication device, etc.

In this example embodiment, because the communication device 120-1 is identified as being a refrigerator requiring low latency channel allocation and low bandwidth, upon request, the communication management resource 140 immediately or within a reasonable time allocates a relatively low bandwidth (2 MHz sub channel A-B having center frequency CF3 in frame #2) to accommodate communications from the communication device 120-1 to the wireless access point 105-1. Conversely, because the communication device 120-2 is known to be a computer device requiring high bandwidth, the communication management resource 140 allocates a relatively high bandwidth (18 MHz sub channel A-D in frame #2) to accommodate communications from the communication device 120-2 to the wireless access point 105-2.

As further shown in FIG. 4, the communication management resource 140 allocates use of the available wireless spectrum in network environment 100 amongst the multiple communication devices over subsequent frames. For example, in frame #3, the communication management resource 140 subdivides a respective 20 MHz channel and allocates 2 MHz of bandwidth (channel A-B, center frequency CF3) for use by the communication device 120-1; the communication management resource 140 allocates 18 MHz of bandwidth (channel A-E, center frequency CF2) for use by the communication device 120-3.

For frame #4, in response to receiving request from multiple communication devices including communication device 120-1, communication device 120-2, and communication device 120-3, the communication management resource 140 increases the overall channel width from 20 MHz to 40 MHz to accommodate the need for high data throughput amongst the multiple communication devices. As shown, the communication management resource 140 subdivides a respective 40 MHz channel and allocates 2 MHz of bandwidth (channel A-B, center frequency CF3) of the 40 MHz channel for use by the communication device 120-1; the communication management resource 140 allocates 18 MHz of bandwidth (channel A-E, center frequency CF2) for use by the communication device 120-2; the communication management resource 140 allocates 20 MHz of bandwidth (channel A-D, center frequency CF4) for use by the communication device 120-2.

Note that in certain instances, the communication device 120-1 may request use of the available wireless spectrum in network environment 100 at a time in which no other devices wish to use the available wireless spectrum. For example, prior to frame #102, assume that the communication device 120-1 is the only communication device that requests use of bandwidth to communicate with wireless access point 105-1. To accommodate the request, the communication management resource 140 subdivides a corresponding 20 MHz channel, and then allocates 2 MHz of the 20 MHz channel (center frequency CF5) for use by the communication device 120-1 in frame #102. Note that a remaining 18 MHz portion of the corresponding available 20 MHz channel in frame #102 is unused by any of the communication devices in communication with wireless access point 105-1. In one embodiment, the unused portion of the wireless bandwidth in frame #102 can be used by another communication device communicating with a different wireless access point.

In a similar manner of allocating a channel and/or one or more sub-channels to the communication devices 120 in the upstream direction as previously discussed, note that the communication management resource 140 can be configured to dynamically allocate use of available wireless bandwidth in the downstream direction to the communication devices 120. For example, as the wireless access point receives communications addressed for delivery to the different communication devices 120, the communication management resource 140 dynamically subdivides an appropriate channel (such as 20 MHz, 40 MHz, 80 MHz, or channel of any other size, etc.) into multiple sub-channels for delivery of communications to the communication devices 120. In such an instance, the communication management resource 140 provides notification to the different communication devices 120 of appropriate bandwidth information and center frequency information for retrieving the downstream communications in the appropriate time frames.

FIG. 5 is an example diagram illustrating cascading of communication devices and partitioning of bandwidth for the cascaded communication devices according to embodiments herein.

As shown in this example embodiment, the communication device 120-1 can be configured to behave as though it was a wireless access point with respect to one or more other communication devices. In this example, when acting as a proxy, the communication device 120-1 receives communications over wireless communication link 127-2 from the communication device 120-4. The communication device 120-1 forwards the communications received from communication device 120-4 over wireless communication link 127-1 to wireless access point 105-1.

For example, as shown, and as previously discussed, the communication device 120-1 can be configured to establish the respective wireless communication link 127-1 to communicate with wireless access point 105-1. Additionally, the communication device 120-4 establishes the respective wireless communication link 127-2 to communicate with communication device 120-1.

During operation, in the downstream direction, assume that the wireless access point 105-1 transmits first communications (such as wireless encoded data packets) to the communication device 120-1 over wireless communication link 127-1. The first communications are addressed for delivery to the communication device 120-1. Because the first communications are addressed for delivery to the communication device 120-1, the communication device 120-1 processes the communications locally and does not forward the second communications to the communication device 120-4.

Additionally, in the downstream direction, the wireless access point 105-1 transmits second communications addressed to the communication device 120-4 to communication device 120-1. Because the second communications are addressed for delivery to the communication device 120-4, the communication device 120-1 forwards the second communications to the communication device 120-4.

In the upstream direction, the communication device 120-1 transmits its own generated messages (such as third communications) as well as additional messages (such as fourth communications) received from the communication device 120-4 (over wireless communication link 127-2) to the wireless access point 105-1 over wireless communication link 127-1. In other words, as previously discussed, the communication device 120-1 relays fourth communications generated by the communication device 120-4 over wireless communication link 127-1 to wireless access point 105-1. Wireless access point 105-1 further transmits the corresponding communications upstream through gateway resource 150 to network 190 for delivery to the appropriate target resource.

As further discussed below, the communication management resource 140 can be configured to vary an amount of bandwidth allocated on each of the wireless communication links 127 to convey the third communications and fourth communications to wireless access point 105-1 or convey the first communications and second communications to the wireless access point 105-1.

FIG. 6 is an example diagram illustrating allocation of bandwidth to multiple communication devices according to embodiments herein.

As shown in this example embodiment, the communication management resource 140 allocates use of channel A-D to convey communications between the communication device 120-2 (device D) over wireless communication link 128 in frame #11. In a manner as previously discussed, the communication management resource 140 can be configured to allocate a channel (such as a 20 MHz channel with center frequency CF1) to support upstream and/or downstream communications.

Assume in this example that the communication device 120-4 communicates a request (such as during or prior to frame #11) for bandwidth to communication device 120-1. In such an instance, the communication device 120-1 forwards the request to communication management resource 140. To satisfy the request for bandwidth, the wireless access point subdivides the available 20 MHz channel to include channel B-C as well as channel A-D. The communication management resource 140 allocates channel B-C for use by the communication device 120-4 in frame #12. The communication management resource 140 allocates use of channel A-D for use by the communication device 120-1 in frame #12. In one embodiment, the communication device 120-1 communicates notification of the allocation of channel B-C and center frequency information CF3 to communication device 120-4. Accordingly, via the relayed message from communication device 120-1, the communication device 120-4 is informed of allocation of channel B-C in frame #12.

Note that the amount of bandwidth allocated for use by the communication device 120-4 in frame #12 can be determined in a similar manner as previously discussed. For example, in one embodiment, the request for bandwidth originating from communication device 120-4 can include network address information 3772. The communication management resource 140 can be configured to perform a similar analysis (based on forwarded network address information 3772 or other unique identifier information associated with the communication device 120-4) as previously discussed to identify appropriate bandwidth to accommodate the communication device 120-4 and transmission of corresponding data to the communication device 120-1.

In accordance with further embodiments, the communication device 120-1 buffers the corresponding data received from communication device 120-4 during the frame #12. In addition to allocating channel B-C during frame #12, the communication management resource 140 can be configured to anticipate the need by the communication device 120-1 to forward any buffered data received from communication device 120-4 during frame #12 to wireless access point 105-1. To accommodate this need, the communication management resource 140 allocates channel A-B in frame #13, during which the communication device 120-1 forwards the buffered data received in frame #12 over wireless communication link 127-1 to the wireless access point 105-1. Accordingly, embodiments herein support subdividing of channels in different time frames to support serial communications to multiple devices.

As further shown in FIG. 6, note that the communication management resource 140 can be configured to allocate use of channel A-D (such as a 2 MHz channel) for use by communication device 120-2 to communicate corresponding data over wireless communication link 128 to wireless access point 105-1.

In accordance with further embodiments, note that the communication management resource 140 can be configured to allocate use of different channels to each of the communication devices along wireless communication link 127. For example, in one embodiment assume that the communication device 120-1 and communication device 120-4 both request use of corresponding available wireless bandwidth at or around the same time. The communication device 120-1 forwards its request to communication resource 140. The communication device 120-4 transmits the request for allocation of bandwidth through communication device 120-1 to communication management resource 140. In a manner as previously discussed, the communication management resource 140 analyzes one or more attributes of the request (such as an application generating the request for transmission of data, network address information assigned to the requesting device, type of data to be transmitted, etc.) to identify appropriate bandwidth to allocate to each of the communication devices 120-1 and 120-4.

In this example embodiment, for frame #15, the communication management resource 140 allocates use of channel B-C (with center frequency CF3) for use by the communication device 120-4 to communicate data to communication device 120-1. The communication resource 140 allocates use of channel A-B (with center frequency CF8) for use by the communication device 120-1 to communicate data over wireless communication link 127-1 to wireless access point 105-1.

In this manner, communication devices such as communication device 120-1 and communication device 120-4 connected in a serial manner can be allocated appropriate bandwidth (such as a sub channel) on as needed basis to communicate data in an upstream or downstream direction.
